Manifold Absolute Pressure/Barometric Pressure Sensor Circuit Low
The engine computer is seeing a very low signal from the MAP or barometric pressure sensor. This usually means a wiring, connector, or sensor problem. It can cause poor running, hard starting, stalling, or bad fuel economy.
You may be able to drive short distances, but engine performance can be poor and the engine may stall. Get it checked soon, especially if the engine runs rough or loses power.
P0107 means the PCM has detected a MAP sensor or BARO sensor signal below the expected range. The sensor may be reading too little pressure, or the circuit may have an electrical fault such as an open ground, damaged wiring, corrosion, or a failed sensor. On some vehicles the MAP sensor is combined with the BARO function, while on others the barometric pressure reading comes from another source in the PCM.
Yes. Dirt, oil, or carbon buildup can block the sensor port and lower the signal reading.
Yes. The engine computer may calculate fuel delivery incorrectly, which can reduce fuel economy.
You can clear it, but the code will usually return if the sensor, wiring, or vacuum problem is still present.
No. Wiring faults, connector problems, vacuum hose issues, and low reference voltage are also common causes.
